java如何从微调器的项调用活动

Question

我有一个由微调器和提交按钮组成的页面。我想实现的是，当用户在列表中选择一个项目并单击submit时，它应该会将用户带到另一个具有webview的布局。微调器中的每个项目都应打开不同的窗口。布局中的html页面

我现在拥有的是从微调器中选择的项目，但我不确定如何对其执行onclick listener

主要活动的代码。java是：

    public class beef extends Activity {

private Spinner spinner1;
private ImageButton btnSubmit;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.beef);


    addListenerOnButton();
    addListenerOnSpinnerItemSelection();

}


public void addListenerOnSpinnerItemSelection(){

    spinner1 = (Spinner) findViewById(R.id.spinner1);
    spinner1.setOnItemSelectedListener(new CustomOnItemSelectedListener());
}

//get the selected dropdown list value
public void addListenerOnButton() {

    spinner1 = (Spinner) findViewById(R.id.spinner1);

    btnSubmit = (ImageButton) findViewById(R.id.imageButton1);

    btnSubmit.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            if(v.getId() == btnSubmit.getId())
            {
                Intent intent = new Intent(beef.this,display.class);
                intent.putExtra("urlpath", "animalbites.html");
                startActivity(intent);
            }
        }

    });

}

}

CustomOnItemSelectedListener的代码。java是：

@Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        // TODO Auto-generated method stub
         if (arg2 == 0) // First item selected
    {
    //Here I need to give an id for the .html file  

    }
    else if (arg2 == 1) // Second
    {
            //Here I need to give an id for the .html file  
    }



    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }

还有显示器。java是：

public class display extends Activity implements OnClickListener {
    private WebView webView;

     @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.webview);

            Intent intent=getIntent();
            String mUrl=intent.getStringExtra("urlpath");
            webView = (WebView) findViewById(R.id.webview);
            webView.getSettings().setJavaScriptEnabled(true);
            webView.loadUrl("file:///安卓_asset/www/"+mUrl);


     }


    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

    }

}
